（在线痴等）hibernate+oracle出现了错误。求解

[classlj]

<property name="hibernate.connection.url">
jdbc:oracle:thin:@localhost:1521:LUJIE
</property>
<property name="hibernate.connection.driver_class">
oracle.jdbc.driver.OracleDriver
</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">HELLO</property>
<property name="hibernate.dialect">
org.hibernate.dialect.OracleDialect
</property>
<property name="hibernate.show_sql">true</property>


我在配置文件里这样配的 错误提示是 必须给用户已个JDBC的连接

[LovePythonic]

你先看看你是用什么方式连接数据库的，dbcp？C3P0?不同的包，配置的属性是不同。检查属性名。。。

[duyu1025]

那把你用session那块贴出来噻，还有错误。。。
用<property /> 这种写法 name 前面 不要写hibernate，用properties文件要加上hibernate

[classlj]

封装好的类

package moxing;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateList {

private static SessionFactory factory;

static {
try {
Configuration cfg = new Configuration().configure();
factory = cfg.buildSessionFactory();
}catch(Exception e) {
e.printStackTrace();
}
}

public static SessionFactory getSessionFactory() {
return factory;
}

public static Session getSession() {
return factory.openSession();
}

public static void closeSession(Session session) {
if (session != null) {
if (session.isOpen()) {
session.close();
}
}
}
}




下面是单元测试

public void testaa(){

Session session=null;
try{
session=HibernateList.getSession();
session.beginTransaction();

User user=new User();
user.setName("A");
user.setSj(new Date());
session.save(user);


session.beginTransaction().commit();

}catch(Exception e){
e.printStackTrace();
session.getTransaction().rollback();
}finally{
HibernateList.closeSession(session);
}

}

看看这行 是什么报空指针吧
java.lang.NoClassDefFoundError

[duyu1025]

session.beginTransaction().commit();

换成 session.getTransaction().commit();

[duyu1025]

你直接关session，干嘛还封闭一层呢，你换成session.close（）看看，自己我试试，这种bug自己调了。

[humijnjie227]

你有加ORCL的class12.jar

[classlj]

[Quote=引用 17 楼 humijnjie227 的回复:]

有加

[kc8886]

可能是你的jar包有问题 换个试试
java.lang.NoClassDefFoundError
分明是找不到类

[xiaozhao32]

<property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>

[classlj]

[Quote=引用 1 楼 xiaozhao32 的回复:]
<property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>
[/Quote]

不对

[xiaozhao32]

property name中去掉hibernate.

[xiaozhao32]

不对的话 贴下错误代码

[饭炒蛋2009]

呵呵 。。。。

[duyu1025]

看你的错误消息也看不出是你配错了啊，确认包都加了没有？ java.lang.NoClassDefFoundError

[duyu1025]

你那样配也没有错吧。。这是我自己配的写的是hibernate.properties
hibernate.connection.username=XXXX
hibernate.connection.url=jdbc:oracle:thin:@172.18.4.18:1521:als
hibernate.connection.password=XXXXXXX
hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
hibernate.myeclipse.connection.profile=myoracle
hibernate.jdbc.batch_size=50

[classlj]

包绝对加进去了

[classlj]

提示出 错误的代码在关闭Session 那一块
